Shipment greatly required by food shop (8)
I believe the answer is:
delivery
'shipment' is the definition.
(I've seen this before)
'greatly required by food shop' is the wordplay.
'greatly' becomes 'very'.
'required by' is a charade indicator (letters next to each other).
'food shop' becomes 'deli' ('deli' can be a synonym of 'food shop').
'very' after 'deli' is 'DELIVERY'.
(Other definitions for delivery that I've seen before include "Manner of making speech or bowling a ball" , "articulation" , "Act of giving birth" , "Shipment" , "Style of speaking" .)
